Modeling and design of an audio amplifier system

Kanth, Chaganti Sarath and Mayor, Tejas Anishwar (2013) Modeling and design of an audio amplifier system. BTech thesis.



Sound amplification is required for variety of reasons. It has many applications in our day to day life. There are a variety of sound amplification techniques and each technique is employed depending on where and what kind of environment we are present. In this project of designing an audio amplifier system, first we studied the need for sound amplification and the basic block diagram of a sound system and its individual blocks. Microphones: their principle, different types, their working and equivalent SPICE models are followed. Thereafter, a brief study about the power amplifiers, their different classes and the PSPICE simulation models of all of them has been carried out. Class B power amplifier is then experimentally implemented to drive a speaker.
